1. A method for deactivating a content-manipulative ink tool pending on a digital marking-surface system, the method comprising:
receiving an ink unit on a digital marking surface of the digital marking-surface system;
determining whether the ink unit is of a shape associated with a deactivation ink tool; and
when the ink unit is of a shape associated with a deactivation ink tool:
identifying preexisting ink-unit content, wherein the preexisting ink-unit content:
is intersected by the ink unit;
graphically indicates, on the digital marking surface, intersected handwritten ink content provisionally to be manipulated via the content-manipulative ink tool;
is defined by a motion of a digital marking device along the digital marking surface between a digit-down-action or pen-down-action location and a digit-up-action or pen-up-action location of the digital marking device;
is associated with the content-manipulative ink tool, wherein the content-manipulative ink tool is configured to, in response to receiving a selection of an item from the content-manipulative ink tool, modify the intersected content; and
is displayed concurrently with the ink unit on the digital marking surface;
determining whether a user-input solicitation mechanism offering selection for the content-manipulative ink tool is displayed as a menu on the digital marking surface in conjunction with the preexisting ink-unit content; and
when a user-input solicitation mechanism offering selection for the content-manipulative ink tool is displayed as a menu on the digital marking surface in conjunction with the preexisting ink-unit content:
canceling the user-input solicitation mechanism; and
deactivating the content-manipulative ink tool.
